To all whomz't may concern:

Be it known that I, WILLIAM F. GONGA- WARE, a citizen of the United States, resid- Other objects will appear from the sub-` joined spectication and claims, in connection with the accompanying drawings, in which Figure 1, is a plan view with parts removed.

Fig. 2, is an elevation, partly in section, showing one series of trays and the distributing pipes; and the concentrates removing system. l v

Fig. 3, is a perspective detail showing on of the adjustable tray supports.

Fig. 4,'is a perspective view of one of the slime spreaders Fig. 5, is an enlarged fragmentary section K of the hopper showing one of the valves 1n position. p

Fig. 6, is a perspective view of one of the distributing boxes.

The invention consists of aplurality of series of superposed trays circularly arranged and mounted on a revoluble frame, and since the construction and arrangement of each series with its complementary adjuncts is the same` the description of'but. 'one series will suiiice for all.

1n suitable bearings 1 and 2, isrotatably. mounted a vertical shaft 3, to which is rigidly secured a frame, consisting of radial arms 4, on the end of each of which is rigidly fixed a pair of vertical standards 5,

'spaced at their upper ends by and secured to a horizontal member 6, onto whichis fastened an annular ring 7 The lradial arms 4, are suitably supported by adjustable rods 8 and 9, and braces 10, are provided to give stability to the frame.

Said members 6, are provided with a groove for the accommodation of a driving rope 12, and extend inwardly beyond the annular ring 7, for the purpose of forming, a support for a plurality of circularly disposed distributing boxes 13, each ofvwhich is furnished with a central groove 14 on its under side as shown in Fig. .6, in which the members 6, fit, these boxes being held against displacement byy angle pieces 15, bolted to the ring 7 and to the boxes. Near the upper end of said Vshaft 3, is fastened a cylindrical hopper 16, provided in the bottom thereof with a plurality of threaded apertures 17,

into which are fitted a plurality of feed pipes18, radiating therefrom and being depressed to the horizontal to cause the slimes conveyed into the hopper 16, to flow by gravity into the distributing boxes, 13, Veach of which is divided into two compartments by a partition 19, and over each of which compartments, a feed pipe 18, extends. Vthin the hopper 16, are pivoted a pluralityof levers 20, provided attheir lower ends with'valves 21, disposed in operative relation to said apertures 17. The lother ends of said levers 20, project beyond the f top of thekhopper, and are provided with horizontal rollers 22, that are arrangedto successivelyy strike against a plate 28, de@

pending from and made fast to a beam 24.,

whereby the levers are moved about their 'f apertures Vin regular succession and hold same closed for a predetermined length of time, as and for purposes appearing herein# after. Springs 25, are provided to hold said levers in normally inoperative position, as shown in Figs. 2 and 5. 'e

Each distributing box 13, is provided on its forward inward corner, and on its rear.- ward outward corner with a verticallyrispivots, thus causing the valves to close the ing nger 26 and 27, respectively, for rep spectively opening and closing `a valve 27', on a water supply pipe 28, in substantially the following manner: The valve stem of the valve 27', isfurnished with a two-armed leverv 2S', one arm of which normally extends I in the path of the lingers 26. During the rotation of the apparatus, the fingers 2G, striking the extended arm ol the lever 28', open the valve 2T, and permit the water to be supplied to each compartment of the distributing boxes, the valve Vremaining open only for a period ot time required for the traverse of the distributing boxes under the discharge nozzle of the supply pipe 28. vl/'hen the hogere 26, strike one arm of the lever 28', the other arm is moved in the path of the lingers 27, which, engaging the saine after the boxes have passed beyond, or nearly so, the nozzle of the supply pipe 28, close the valve 27. The operation of opening and closing the valve 2?', proceeds successively in alternation during the operation of the apparatus, and practically with the closing l:ind opening oi the valves 21, iii the hopper 16; that is to say, the finger 26 opens thevalve 27 substantially coincident with the engagement and rocking of the lever 20 bythe plate 23 inclosing the valve 21, with the latter held closed during the time thevalve 27' is open. rllhe valve 21 is designed to be held closed a short time after closing of the valve 27 by the Finger 27 as willv appear hereinafter. The iioor ot each compartment or" each distributing box 13, is inclined to cause the material supplied thereto to flow to the end thereof, and depending from each end of the distributing boxes 13, is a series of distributing pipes 29, the ends 30, of which are extended outwardly and in a direct line with the apexes of a plurality of if-shaped angularly disposed spreaders 31, fastened between each pair of vertical standards 5, and which spreaders serve to spread the material to be treated over a plurality of inclined plates 32, which are mounted on the rear ends oi 'll-amis 33, which are pivotally and adj ustably mounted. in said standards 5, and the branches oi which form supports for a plurality of preferably inclined trays 311, suitably covered, and the inclination of which may be regulated according to need, by such adjustable arnis.

. The adjustment of tiie inclination of the arms 33 and the trays 31l thereon isl effected by means of a downwardly and rearwardly extending supporting bar 50 which is ypivotally connected at 51 to the arm and is formed with a series of teeth or serrations 52, which serrations, are adapted to engage a pin carried by the post 5, as*V particularlyy shown in Fig. 3.

The front edges of the inclinedplates 32',

are elevated a suiiicient distance from,i the` arms-33, to enable the traysfto be slid or inserted therebetween andi be held thereby Without anyl other orV permanent4 fastening.

After the,tailings-havegbeen-washed away,

the concentrates remain on the trays andl naaeaei these are washed oil into receptacle A, by a plurality of sprays, issuing trom branch pipes 35, lying in the same parallel plane as the trays 3i, and connected with a vertical pipe 3G, to which water is supplied through a hose 37. This pipe 36, is mounted on a grooved roller 38, traveling on a doubly inclined track in the upper end of said pipe 36, is secured a stem e0, to the lower eiidvof which is pivotally connected one end ot a link l1, the other end of which is pivotally attached to one end oi? a carriage Lil-2, arranged to move reciprocably on ay trackivay a3. To the other end oic the carriage a2, is pivotally attached one end of a similar link ist, the other end ot which is pivotally connected to the upper end oit said stem 4&0. By this link arrangement, the vertical position of the pipe 3G, and the position of the branch pipes 35, relatively to the trays, is always maintained during the movement thereof on the doubly inclined track rlhe reciprocation of the carriage 42, and its complementary parts, is accomplished by a rod 45, connected toa suitably journaled eccentric wheel 16, and with one end oit the carriage, the eccentric wheel receiving power from chain il?, running' over a suitable drive wheel ell-3.

y riihe concentrates removing sprays from the branch pipes 35, do not begin to play on the trays 3st, until the wash water from the distributing boxes 13, has ceased to flowv through the distributing pipes 29, The rays at that time successively travel within the range of the reciprocating sprays,which by back andi-Orth moifenient in radial relation to the rotating frame and the trays thereon, wash oli' the concentrates that fall into the receptacle A. @bviously those `valves 21, within the hopper 16 controlling the flow ci material to the trays through the 1.istributing boxes 13, must be closed and remain closed during the operation ofthe sprays, and this is accomplished in the manner hereinbefcre setl out, bythe plate 23,

which moves the levers `2O, and holds the from, and especially to removethe tailings from theitraysprior to the concentrates removing operation otthe sprays.
